BED-BOTTOM CASTING.

SPECIFICATION forming part of Letters Patent No. 61 ,411, datedSeptember 27, 1898.

Application filed July 20, 1897. Serial No. 6%,270. (No model.)

To all whom it may concern:

Be it known that I, LEMUEL E. IRISH, a citizen of the United States,residing at Greenville, in the county of Montcalm and State of Michigan,have invented certain new and useful Improvements in Bed-BottomCastings; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of myspecification.

My invention relates to bed-bottoms and attachments therefor whereby thebed-bottom is securely held in place and is easily and quickly removedwhenever it is desired; and my invention consists in the novel featuresof construction and arrangement of parts hereinafter fully described andclaimed.

Similar numerals refer to similar parts throughout the specification anddifferent views of the drawings.

Figure 1 is a perspective view of the bedbottom and T-bars. Fig. 2 is alongitudinal section of the bed-bottom. Fig. 3 is a detail perspectiveof part of the casting at one end of bed-bottom. Fig. lis a detailperspective of the arm pivoted to casting shown in Fig. 3. Fig. 5 is aperspective of casting at the other end of bed-bottom. Fig. 6 is adetail perspective of the T-bar. Fig. 7 is a perspective of V-shapedlinks, showing the apex bent down and Fig. 8, a longitudinal section ofspring and stop-links. Fig. 9 is a side view of bar-link.

The body of the bed-bottom is composed of transverse rows ofsubstantially V-shaped links 1. The apex of each link is formed into arounded eye 2, which is bent downward the thickness of the Wire of whichthe bed-bottom is composed.

In the body portion of the bed-bottom the eye 2 is nearly but not quiteclosed, a sufficient space being left to receive the terminals 3 of thelinks of the row next adjacent, connected to said eyes in the mannershown when the bed-bottom is in afolded condition. These terminals aremade parallel for a short distance in order that they may nicely fitinto the open spaces of the eye 2 when the bed is folded. It will benoticed that the end row of links into which the coiled springs 4 arehooked have the eye 2 entirely closed, the wire being crossed andtwisted, with the ends extending in'opposite directions, whereby acomplete ring is formed. By this construction the springs are preventedfrom slipping out of place when the bed-bottom is folded and the form ofthe eye is kept intact when the transverse bar-link 5 connects thecoiled springs in the manner shown. The object of this bar-link is toprevent thelinks of the bed-bottom from being spread apart while beinghandled and thereby being injured or bent out of shape, thus causing thenetting to become tangled and damaged. This is an important feature, asit is my purpose to provide a bed-bottom which shall be easily rolled,handled, or folded without any of the parts being injured or. displaced.Within each coiled spring 4 are links which are looped together and ateach end connected to the respective end of the coiled spring. One endof the spring is passed through an aperture in the T-bar and given atwist with which one end of the stop-link engages. The other end of thespring passes through the eye 2 and forms aloop into which the other endof the spring 4 hooks. By this arrangement should the bed be heavilyweighted and the tension of the coiled springs be at their limit theweight will be thrown upon the stop-links, and the springs thereby willbe relieved of any undue strain. Particular attention is called to themanner in which the stop-links and the springs are connected, as abovedescribed. The purpose of this arrangement is, first, to check thetension of the spring inside of its life when overweighted, and, second,to prevent the hooks in the end of the spring from being drawn out orstraightened when subjected to an overstrain, as is the case in myPatent No. 566,180. Constructed and united in the manner set forth thelinks and springs have a twofold object and thereby accomplish a newresult.

7 represents the castings for one end of the bed-bottom, and 8 thecastings at the other end, which consist of a flat strip 20, having astop or rest 12 and arms 13 pivoted thereto. The castings 7 are formedwith a slot 9 and a recess or depression 10, whereby a shoulder 11 isformed, as shown in Fig. 5. The castings 8, or more particularly thefiat strips, are formed with a stop or rest 12, and to these castingsarms 13 are pivoted. These arms have enlarged ends, in which, on theinside, are slots 14, and when in position rest upon stops 12. The slots9 and 14 in the castings are formed to receive the web 15 of the T- bar,while the flanges 16 rest in the recess 10 of the castings 7 and againstthe outer ends of the pivoted arms 13. The shoulders 11 prevent theT-bar from undue lateral movement when the parts are all in position.The stops or rests 12 on the flat strips 13 of the castings 8 arelocated in the inner lower corner of the casting a little below thedead-center line of the pivoted arm 13. It will be seen that when theT-bar engages the castings 7 at one end and the T-bar at the other endengages the arms 13 and the arms 13 are sprung back into position andrest on the stops 11 the weight on the bed-bottom will securely hold thesame in place, since the stops are below the dead-center line. When itis desired to remove the bed-bottom, the

T-bar carried by the pivoted arms is grasped 1 tion is animprovement onmy patent covering a wire hammock, No. 566,180. I do not herein makeclaim to any construction shown and described in said patent.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a bed-bottom haying end T-bars and pivotedcastings at one end having slots at the inside of the outer ends andfixed castings at the other end having like terminals, the webs of theT-bars fitting said slots, all arranged as set forth.

2. The combination of a bed-bottom having T-bars at each end thereof,castings at one end including pivoted bars slotted in their outer endsand a fixed casting at the other end having like slots, the webs of theT-bars fitting said slots and being removable therefrom, and stops belowthe dead-center of the pivoted bars, all arranged as set forth, wherebythe bed-bottom is sprung taut into position and is readily removed whenthe pivoted bars are lifted up.

3. The combination of abed-bottom having end T-bars, castings at one endhaving slots into which the web of the T-bars fits, and rethe other endhaving slots in which the web of the other T-bar fits, all arranged asset forth.

4.. The combination of a bed bottom terminating in T-bars, castings atone end having slots in their outer ends receiving the web of theT-bars, castings at the other end having a limiting-stop at their innerends and a stop or rest at their outer. ends below the deadcenter line,said latter castings including pivoted bars having slots in their outerends into which the web of the T-bar fits, all arranged as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

LEMUEL .E. IRISH.
